Penthouse Player (Billionaire Bosses #1) by Tara Leigh

Abandoned by her mother and spurned by her father, Reina St. James is tired of being treated like a dirty little secret. It wasn’t easy making her way into the high-risk, high-reward Wall Street world ruled by financial kings and trust fund tyrants. But now that she’s got a stiletto-clad toe into one of the swankiest firms in Manhattan, Reina is determined to prove she’s more than just a pretty face hiding an ugly past.

For Tristan Xavier Bettencourt IV, escaping the shadow cast by generations of family fortune has been difficult, and success hasn’t come without sacrifice. Tristan has always put business before pleasure… Until Reina’s curved lips prove an invitation he can’t resist.

Walking away from their explosive night together won’t be easy, even if the heat between them might consume both of their careers. Will Reina and Tristan risk everything by betting on each other?
